Les Ruines by Scott Smith

A vacation to an isolated Mayan ruin turns into a nightmare when a small group of travelers becomes trapped atop a sinister, living tangle of vines that wound and infect them, cutting off escape and any hope of outside help; as injuries, infection and fear escalate, the friends descend from solidarity into suspicion and brutality, forced into horrific choices to survive while the novel probes claustrophobic dread, the fragility of civilization and the ugly instincts that emerge under extreme pressure.
